BOSTON – Single-family home sales in Bristol County, Mass., rose 20 percent, and the median sale price increased 7 percent in August compared with the same period last year, The Warren Group said Tuesday.

There were 317 houses sold last month, up from 264 in August 2011. The median sale price of those homes, $235,000, was up from $225,000 in last August.

Sales volume in Bristol County has risen four consecutive months, but this is the first month during that period that median prices have also gone up.

Bristol County sales closely tracked statewide volume, which also rose 20 percent year over year for Massachusetts. The median single-family sales price in the state rose 2 percent in August to $310,000, from $305,000 in August 2011

“One more month of strong home sales confirm speculation that the housing market recovery is underway,” Warren Group CEO Timothy M. Warren Jr. said in a statement “Even though we are comparing to a slow August last year, the consistent sales volume of 4,000 to 5,000 in the past few months is a promising indicator.”

In the condominium market, August sales rose 65 percent in Bristol County – from 37 sales last year to 61 last month. The median Bristol County condominium price increased 20 percent year over year to $712,500.

Statewide, condominium sales rose 40 percent in August from August 2011, but the median condo price fell 4 percent year over year to $279,000.
